|The ion line channel.|
At the F-region peak, plasma lines show up nicely already after a few seconds of intergration, which offers a way to accurately calibrate received power with very high time resolution.
The only problematic thing that we noticed is that the antenna or feed gain seems to be somewhat lower on the top end of the band, which causes the up-shifted lines to be attenuated.
